The fear of going to the doctor seems to translate beyond humans. As these family pets show, their absolute fear of visiting the vet is a true angst-ridden event. Only difference when humans are terrified we are called wimps, when dogs are frightened its adorable.
I know you're up to something.
You just look guilty.
I'm scared. Hold me.
Maybe they won't see me.
I wonder if I could fit through that drain.
I'm not leaving here.
Please just go away.
No one can see me now.
Garbage cans may be a good place to hide as well.
Cabinets are a good choice, but closing the doors might help.
